What will I learn?
Master the essentials of building a small compiler from scratch with this focused, hands-on course. You will design grammars, implement a lexer and recursive descent parser, build clean ASTs, and generate stack-based VM instructions. Through clear pseudocode, end-to-end examples, and practical debugging tools, you will gain reliable, reusable skills for creating robust, extensible language tools fast.
Elevify advantages
Develop skills
- Build a MiniCalc lexer: fast tokenization with robust error reporting.
- Implement a recursive descent parser: clean grammar, AST creation, and recovery.
- Design and validate ASTs: safe node models ready for analysis and codegen.
- Generate stack-based VM code: map AST nodes to efficient PUSH/LOAD/STORE ops.
- Ship a full MiniCalc compiler: end-to-end tests from source to VM execution.
